Looking for an across the network Desktop/My Documents backup solution

We are currently looking into removing roaming profiles from the equation here at my site, but we still would like to backup user's desktops (Must specify here that I mean %systemdrive%\documents and settings\%username%\desktop) and my documents.

I am open to all solutions involving the backup of User Desktops/my documents across the network onto a backup server.

In this case, reliability trumps cost so please let me know what the best solution here is.

What server os are you useing? If you have active directory you can use Group Policy to redirect the desktop and My Documents folder to the server. Go to group policy create a new policy and go to user configuration\windows settings\folder redirection and set the path to where you want to store the files.
